The removal of "pip install -U pip" from the commands section appears to be unintentional. While setuptools and wheel are now upgraded in the commands_pre section, pip itself is no longer being upgraded. Consider adding "pip install -U pip" to the commands_pre section to ensure pip is also up-to-date before running tests.

.github/workflows/publish_pypi.yml:16

• The workflow still uses deprecated GitHub Actions majors (actions/checkout@v2 / actions/setup-python@v2). These are out of support and may miss security fixes; update to the current supported majors (e.g., checkout v4 and setup-python v5).

      runs-on: ubuntu-latest
      steps:
        - name: Checkout
          uses: actions/checkout@v2

.github/workflows/publish_pypi.yml:30

• Publishing uses pypa/gh-action-pypi-publish@master, which is a moving target and a supply-chain risk (the code you run can change without review). Pin this action to a specific release tag or, preferably, a commit SHA.

          run: python setup.py sdist bdist_wheel

Using ubuntu-latest makes the build non-deterministic because the underlying OS image will change over time (and can break CI/publishing unexpectedly). Prefer pinning to a specific Ubuntu version (e.g., ubuntu-24.04) and updating it intentionally when needed.

Suggested change

	runs-on: ubuntu-latest
	runs-on: ubuntu-24.04

[Copilot]

The added "Install build tools" step installs setuptools/wheel with a >= spec and --upgrade immediately after installing pinned versions from requirements/pip.txt. This can silently override your pinned/toolchain versions and reduce reproducibility; either rely on requirements/pip.txt alone or pin the versions in this step to match that file.

Suggested change

	- name: Install build tools
	run: pip install --upgrade "setuptools>=65" "wheel>=0.38"

Switching CI to ubuntu-latest can introduce unexpected OS-level changes over time. Prefer pinning the runner image to a specific Ubuntu version (e.g., ubuntu-24.04) to keep CI stable and upgrades deliberate.

Suggested change

	os: [ubuntu-latest]
	os: [ubuntu-24.04]

Even with the runner change here, this workflow is still pinned to deprecated GitHub Actions majors (actions/checkout@v2 and actions/setup-python@v2 later in the file). Update them to the current supported majors (e.g., checkout v4, setup-python v5) to stay supported and receive security fixes.
